I hope to post once per week for the rest of the season.
To get the elephant (Doncic) out of the room... this formula uses four basic inputs: Win Shares, VORP, the average of +/- and On-Off, and team wins. Three of these four are cumulative, whereas the the average of +/- and On-Off is Per100. This means that +/- and On-Off will take on relatively less weight as the season goes on, while Win Shares, VORP, and team wins will take on relatively more weight. Currently, Doncic is by far the lowest among these twelve in the average of +/- and On-Off. The formula matches the last eight MVP's, so it should be fairly reliable when stretched over an 82 game season.
I chose to use +/- and On-Off instead of RAPM as I did in my old formula for the following reasons. First, RAPM is not always easy to find on the internet. Second - crucially - different sources for RAPM consistently give different results. I had a strong preference for a number that I could easily find on basketball-reference.com.
But the real impetus for changing my formula was the fact that I snafu'd my 2019 spreadsheet. I ended up with a spreadsheet that did not match the final results I posted on RealGM. The results matched the spreadsheet when I posted them, of course, but at some point after the season ended, I altered the spreadsheet. No matter how hard I tried, I couldn't get them to match again. My sheets going back from 2018 to 1997 were all consistent with my RealGM posts, but 2019 was not. There were two possible reasons for the confusion. First, the aforementioned different sources for RAPM: I was unable to determine with certainty where my numbers had come from. (The formula also included a couple of calculations between RAPM and total possessions, which further complicated my search for the correct source.) An even bigger problem was that I was posting 20 names on RealGM, while using a spreadsheet with 34 names - with some names alternating on and off of the spreadsheet from week to week... using a formula that averaged out the scores of the 34 names! So, to find the correct formula, I would have had to find the exact 34 players who gave me the results for the twenty names I posted on RealGM. Long story short, I was unable to even determine the source of the confusion, much less to ameliorate it. Besides my natural affinity for basketball-reference, not being able to reconcile my 2019 results was the biggest motivator in changing my formula. My new formula will be much easier to handle, because it no longer averages itself with the other names in the ranking. I can simply plug in a name, plug in the numbers, and I'm done. Another nice bonus to this approach is that cross-season comparisons are more straightforward.

The minimum MVP score seems to be 23, while 26 seems to be about average. To put their current scores into perspective, that's the range that these players are racing toward. (I.e., there's a long way to go.)
For further perspective - and for fun - here are the most recent winners based on this formula. Ten of these eleven also won the actual MVP, with 2011 being the lone exception.
33.35 - LeBron James, 2009
31.30 - Stephen Curry, 2016
29.82 - LeBron James, 2013
29.81 - LeBron James, 2010
26.90 - Stephen Curry, 2015
25.76 - Kevin Durant, 2014
24.08 - Russell Westbrook, 2017
23.84 - LeBron James, 2011 (the MVP was Derrick Rose, whose score is 18.98)
23.33 - James Harden, 2018
23.06 - Giannis Antetokounmpo, 2019 (James Harden is 23.04)
22.99 - LeBron James, 2012 (the shortened season lowers his score)
At some point, I will begin a thread in the Player Comparison board that revises my results going back to around 2002, with the top twenty finishers for each season.
